Introduction The 7D13 Digital Multimeter plug in unit is designed for use with Tektronix 7000-series Oscilloscopes equipped with a readout system. The 7D13 can be used to measure DC voltage. DC current, resistance, and temperature. Temperature measurements are made with the P6058 probe or a temperature-sensing device connected to the front-panel PROBE connector. An analog temperature signal output is available at the front-panel TEMP OUT connectors regardless of the setting of the MODE/RANGE control. The output of the 7D13 is presented as a digital readout on the CRT of the associated oscilloscope, along with information encoded by the other plug-in units. This display is written by the CRT beam on a time-shared basis with the analog waveform display from the other plug-in units.
